[man] fix bogus markup

Summary:
Replace `$(u,...)` with `$(i,...)` since `$(u,...)` doesn't exist.
Cmdliner was emitting a warning at runtime:

  cmdliner error: Unknown cmdliner markup $(u,...) in "Specify classes where the destructor should be ignored when computing liveness. In other words, assignement to variables of these types (or common wrappers around these types such as $(u,unique_ptr<type>)) will count as dead stores when the variables are not read explicitly by the program. (default: $(i,[]))"

[release] preparing for binary releases

Summary:
Change the documentation to refer to (upcoming) binary releases. Update the
scripts to treat .release differently: now we want to build clang and the
plugins even in release mode, as that's just the preparation for the release
tarball containing only binaries.
